Conditions with wind speeds greater than 74 mph meet what type of warning?

When wind speeds exceed 74 mph, the conditions align with a Hurricane Warning. This warning is specifically issued when a hurricane is expected to affect an area, with the potential for extremely dangerous conditions and damage. The key defining feature of a hurricane is sustained wind speeds of 74 mph or more, along with a significant threat of storm surge, heavy rainfall, and flooding.

In contrast, other types of warnings listed pertain to different weather phenomena. A Severe Storm Warning typically addresses severe thunderstorms, which may include damaging winds, but they do not reach the intensity associated with a hurricane. Thunderstorm Warnings focus on imminent severe weather stemming from thunderstorms, but they generally do not indicate the sustained high wind speeds characteristic of hurricanes. A Tornado Warning is specific to tornadoes, which can produce extreme winds in localized areas but are distinctly different from sustained winds caused by hurricanes.

Thus, understanding the classification of weather conditions and the specific wind thresholds associated with them helps correctly identify when a Hurricane Warning is warranted.
